We used no heating in August, so only hot water and cooking.
I read the meters in our rented house on 1/8 and 31/8.
In 30 days we used 347kWh of gas, 11.57kWh per day. The boiler is an ancient Potterton Netaheat 10-16 Mk2 F, which as far as I can deduce is 30+ years old. The hot water is hot, but not scalding - tank stat is at 50-55, boiler stat is only numbered 1-5 and has been on about 1.5 all summer. I'll put that up a bit when the heating is on regularly.
Despite its age it is apparently fairly efficient. It uses spark ignition rather than a pilot light and has a fanned flue, and makes a hell of a noise when it fires.
